Z Claims?. (Cli 8.5-32) 'This invention relates to a joint` tightener; and fastener, and may be regarded' as. an improvem'ent'over the constructions disclosedyin myr co*- pending application Serial No. '57;63143vii1ed`No'- vemberl, 19148.

The primary purpose of theconstruction here'- (in disclosed is to. provide a ymeans that can be easily andquickly Ainstalled in two planar-.meme bers,\ and' which willltighten and hold the planar rmembers in abutting relationship. In theA in- `stallation. of" counters,. wall cases,v wainscoating and the like, sections thereof may becompletely constructed andv nished Yat a plant or. factory and transported'. as sectionsto the locality of'in.- sta'llation. It is then desirable to fasten .and tighten' the end edges .of such constructionsL in abutting relationship.

Specifically, an object ofthe presentinvention is to provide animproved joint ti'ghtenerA and fastener which vis so designed and constructed that the partsdthereofcan be easily formedv on punch presses, automatic screw machines.. and the like which. wilI enable the elements, ofthe tightener and fastener 'to 'be very easily and economically, manufactured: and' assembled: At the same time the device is so designed as to afford adequate vbearing surfaces, it.. being. understood that these tighteners and fasteners are usually installed in wooden constructions.

Withzthe foregoing andxother objects inyiew, which willbe mademanifestf inthe follow'ingfdetailed"y description and. specicallynpointed. out in thel appended Claimareerence .isafhad toftlf'iezv accompanying drawing. for. an illustrativeembodiment of'th-e linvention whereim:

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, I and II indicate two planar members that are to be joined together in abutting relationship at their opposed end edges I2. These planar members may be parts of counters, Wall cases, Wainscoting, or similar structures, and which may have their forward faces indicated at I3 and I4 completely'iinished prior to the time of installation. It is desirable 2,. to connect the members 'IIJ land I-If lnabutting. relationship withoutmarring-or dekf'acing the=n ishedorwardfaces' I3 andv 14. The memberswllr and II mayor may not be vequipped with dowel pins I5 in their edges I 2.

The'improved joint tightenerfandfastener consists of a bolt generally indicated; at I6; one-end of which is threaded1 as indicatedV at I1 v'for-'farrproxlmatel'y-onehhalf the length-'ofthe bolt'. LThe other halfl of the bolt is non-circular in Aform 4as indicatedy at I8 exceptl for-7a relatively jnarrow neclc I9'which may becylindrical. Theiboltused may be formed from squar-st'eel stock-andv-the neck I9, as well as the threads I1z may be cut thereon on 4an automatic screwmachine; thus enabling the bolt" to be easily' and' economically manufactured.v 'The ends of the boltare receivable in holes 2U. and 21 drilled into :the edgesiof the planar members H) vand II. Thesehol'es are drilled to such a depth. that their combined depths exceeds thelength offthe'lbolt- I6 The non-circularv end of the bolt .is adaptedt to be 'lockedin position inr its Aho-le'Zll by'means'of'l a cylindrical, key or checkV .22: This` check is formed of sheet' metal stamped and'formedf or Vrolledinto cylindrical form. It hasspaced ends 23.*and24 which arespaced from eachother a distance substantially equal to 'thezwidth ofth-e non-circular. portion. I'B. Diametrically opposite the space between these spaced endstheA key or .checkis recessed; as at 25,' 'the width, of the recess .beingsubstantially equal to the diameter of the .cylindrical portion, L8'. This ykey orr chf-:clitk is adapted'tjo be. recessed' in the .rear face'l of the ,plana-r member Ill by drilling `a hole .262m the rear. faceand which. does not. extend. through to theforwardlface 1.3,'. vThejhole 26hasa diameter approximately. equal to .theexternal diameter. of thefkey or check. When the bolt. I.6.,is. ins'talled in. the .hole 20,. the check can be. slipped'laterally with. respect thereto in` the hole 26. The recess 25 accommodates the circular portion I9 andthe `innen faceef-.thecheck-adjacent the recess is adapted to abut against the shoulder 21. The opposed ends 23 and 24 fit snugly against the sides of the squared ends of the bolt and hold the bolt against rotation. As the cylindrical check ts the hole 26 rather closely, the ends 23 and 24 will not spread or permit rotation of the bolt I6 even though a high torque is applied thereto.

In the rear face of the other planar member II there is drilled a similar hole 28. This is designed to receive a cylindrical nut holder 29. The nut holder 29 is likewise formed of sheet metal stamped and bent into cylindrical form and has opposed spaced ends 30 and 3| which are notched as at 32 and 33, respectively. Diametrically opposite the space between these spaced ends there is an aperture 34. A nut 35 has protuberances constituting trunnions 36 and 31 on the ends thereof concentrically arranged with respect to the bore through the nut. The trunnion 36 is adapted to be inserted in the aperture 34 and the trunnion 31 is adapted to be sprung between the ends 30 and 3| to assume a position in the notches 22 and 33. In this manner, the nut and nut holder can be easily and quickly assembled together and the nut Will be rotatably mounted in the nut holder.

The nut has the bore therethrough only partially threaded as indicated at 38, the remainder of the bore being enlarged. The threads in the nut are complementary to the threads on the threaded end l1 of the bolt. Radial holes 39 are Y drilled in the nut, there preferably being six of such holes circumferentially spaced thereabout. Each of these holes is capable of receiving a small section of drill rod or the equivalent indicated at 40 enabling the nut to be forcibly rotated or turned on the bolt. l

It will be appreciated from the above-described constructions that the nut itself may be produced as an automatic screw machine product except for the holes 39. These holes may be simultaneously drilled in the nut on a radial drill and as their inner ends terminate opposite the enlarged portion of the bore through the nut, it is not necessary to remove therefrom any burr that might be formed on the interior of the nut as a result of this drilling. The nut holder, like the key or check, can be formed readi= ly from sheet metal stock automatically on a punch press and the assembly of the nut with the nut holder is very easily and quickly accomplished.

In installing the joint tightener and fastener the holes and 2| are drilled in the planar members and the holes 26 and 28 are drilled in the rear faces thereof. The nut holder is first slipped into the hole 28 and the bolt is started in the nut. The non-circular portion of the bolt is then positioned in the hole 20 and the key or check 22 inserted in the hole 26, thus locking this end of the bolt against rotation and against withdrawal from the hole 20. The drill rod 49 may then be applied in the holes 39 of the nut and the nut rotated so as to screw onto the bolt, thus drawing the planar members I0 and l l into tight abutting relationship. Although a considerable tension may be thus developed on the bolt to hold the planar members in tight abutment due to the relatively broad bearing surfaces afforded` by the nut holder and by the check substantially ntting in their respective holes 26 and 28 the wood of the planar members will ordinarily not be deformed or partially destroyed even though the nut is screwed up on the bolt with considerable eiort.

From the above-described construction it will be appreciated that the improved joint tightener and fastener is so designed that its nut and its bolt can be easily and economically manufactured as automatic screw machine products. The check and nut holder can be readily produced on a punch press and the assembly of the nut with the nut holder is highly facilitated. These parts, when assembled together, will not readily separate and become lost from each other.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as defined by the appended claims.

In a device of the class described, a nut holder comprising a cylindrically-shaped section of sheet metal having oppositely notched ends slightly spaced from each other and having an aperture diametrically opposite the space between the ends, a nut having a threaded bore therein, said nut being disposed within the nut holder and having cylindrical trunnions on its ends coaxially arranged with respect to the threaded bore of the nut, one of said trunnions being rotatable in the aperture of the nut holder and the other of said trunnions being rotatable between the notches in said ends, and means whereby the nut may be rotated in the nut holder.
